    Abstract:
    BACKGROUND: Interferon-induced depression represents a major complication in antiviral treatment of chronic hepatitis C virus (HCV) infection. AIM: To evaluate in a placebo-controlled study the efficacy of a selective serotonin reuptake inhibitor (SSRI) in HCV patients on antiviral therapy with interferon-associated depression. METHODS: 100 HCV outpatients were included in a randomised, double-blind, placebo-controlled study. During interferon therapy (peginterferon alpha-2b plus ribavirin), depression was monitored using the Hospital Anxiety and Depression Scale (HADS). Patients with clinically relevant interferon-induced depression (HADS >or=9) were randomly assigned to placebo or citalopram (SSRI, 20 mg/day). RESULTS: In 28 patients (28%), HADS scores increased to >8 during interferon therapy. They were treated with placebo (n = 14) or SSRI (n = 14). HADS scores declined significantly in SSRI patients within four weeks of therapy (p<0.001) but not in placebo patients. This difference between subgroups was statistically significant (p = 0.032). Unblinding became necessary in five placebo patients as a result of intolerable depression. Rescue medication (20 mg citalopram) led to a significant decrease in HADS scores (p = 0.008). All citalopram patients were able to complete interferon therapy as planned. As an interim analysis showed a significant superiority of SSRI over placebo, the study was terminated prematurely. Three patients, who became depressed afterwards, were treated in an unblinded fashion with citalopram. CONCLUSIONS: The findings demonstrate clearly that citalopram treatment is highly effective in HCV patients on interferon therapy, when initiated after the onset of clinically relevant depressive symptoms. This suggests that a general SSRI prophylaxis is not necessary in these patients.
